Cwejman VCO-6

With the VCO-6 Cwejman offers an oscillator that gives you access to all waveforms simultaneously. Furthermore, besides exponenetial FM it offers linear FM, a feature that mayn people missed on the VCO-2RM. A specialty is the pulse width department having two pulses with individual PWM modulation and a sawtootch with PWM.

We currently do not accept pre-orders for Cwejman products. If you are interested in this module, please use the availability notification. The number of Cwejman circuits is limited. Therefore, we recommend you to order online IMMEDIATELY when a module becomes available. Enquiries via e-mail or telephone are usually not fast enough. (More detailed information can be found on the product page.)

Oscillator tuning:
A rotary potentiometer with six positions is used to switch octaves, the frequency is set more exactly (±12 semitones) with the fine tune potentiometer. A switch activates LFO mode.
There are two exponential FM inputs with attenuators; fully clockwise they have a characteristic of 1V/octave
The linear FM input also has an attenuator and van be either AC or DC-coupled, depending on swith setting i.e. the linear FM works with Audio or CVs.

Pulse width modulation:
Pretty uncommon is that the PWM section is extensive and offers some nice functions: There are no less than three waveforms whose pulse width can be modulated; number 1 one pulse and a simultanously modulated sawtooth and number 2 another pulse wave. Pulse 1 and sawtooth share the PWM 1 input; 2nd pulse has it's own PWM 2 input. The PWM control can be assigned either to 1 or 1&2.

A sync input for hard oscillator synchronisation is available of course.

All Cwejman modules are protected against reversed polarity.
